Subject: Re: AW: Re: Automated CPA Negotiation
Michael, Thank you again for your interest. I have inserted answers to your questions below. I have sent copies of this to the ebxml-cppa-negot list and ebxml-cppa-comment list. You should be able to subscribe to the ebxml-cppa-comment list without being a member. This will allow you to submit questions to the CPPA team and negotiation subteam, receive answers, and receive any other discussion on that list.. You won't be able to subscribe to the ebxml-cppa-negot list without becoming a member of OASIS. To subscribe to ebxml-cppa-comment, send a message to ebxml-cppa-comment-subscribe@lists.oasis-open.org. The subject and body of the message can be blank. Please let me know if you have any problems. I will announce the next draft on ebxml-cppa-comment. I will either send you a copy or tell you how you can get it from the web site if non-members can download documents. See below for my answers.

MWS: The CPPA template must contain values that are valid to an XML parser. However the presence of an element or attribute description in the NDD that accompanies the CPA Template initial offer overrides the value of the same element or attribute in the CPPA template. >-Are the preference functions of both partners in a single matched NDD >that is part of the (counter-)offer with a CPA-template? MWS: There are some rules on order of preference when several alternatives are given in the NDD. See, for example, section 11.4. See also my reply below. >-Are there elements for a total utility function and a minimum total >utility value in the NDD? This would give the negotiation algorithm a hint >to decide on several elements with preference functions. MWS: Version 1 of this specification will cover only the negotiation protocol (message exchanges and rules for working with the NDD) and not the negotiation algorithm. As mentioned in section 14 (Negotiation Algorithm), the negotiation algorithm, including entities such as utility functions, is out of scope for version 1. In version 1, the negotiation algorithm is viewed as a private strategy matter of each party. Admittedly, the specification would be much more powerful if it included negotiation strategy functions. However the sub-team's consensus was that it would be best to start with the functions that are in the draft and leave the much harder negotiation strategy problem for a later stage. I am hopeful that version 1 has enough functionality to be useful and might attract experts, such as yourself, on the higher level negotiation functions, who might wish to contribute to standardizing that level of negotiation. >Please inform us when the new version of the specification is available. > >Do you have any information on the current state of "JSR 157 - CPPA Java >component"?
